IBM has come up with an automatic debating system called Project Debater that researches a topic, presents an argument, listens to a human rebuttal and formulates its own rebuttal. But does it pass the Turing test? Or does the Turing test matter anymore?
The Turing test was first introduced in 1950, often cited as year-one for AI research. It asks, “Can machines think?”. Today we’re more interested in machines that can intelligently make restaurant recommendations, drive our car along the tedious highway to and from work, or identify the surprising looking flower we just stumbled upon. These all fit the definition of AI as a machine that can perform a task normally requiring the intelligence of a human. Though as you’ll see below, Turing’s test wasn’t even for intelligence or even for thinking, but rather to determine a test subject’s sex.
The rumor mill has recently been buzzing about Nintendo’s plans to introduce a new version of their extremely popular Switch console in time for the holidays. A faster CPU, more RAM, and an improved OLED display are all pretty much a given, as you’d expect for a mid-generation refresh. Those upgraded specifications will almost certainly come with an inflated price tag as well, but given the incredible demand for the current Switch, a $50 or even $100 bump is unlikely to dissuade many prospective buyers.
But according to a report from Bloomberg, the new Switch might have a bit more going on under the hood than you’d expect from the technologically conservative Nintendo. Their sources claim the new system will utilize an NVIDIA chipset capable of Deep Learning Super Sampling (DLSS), a feature which is currently only available on high-end GeForce RTX 20 and GeForce RTX 30 series GPUs. The technology, which has already been employed by several notable PC games over the last few years, uses machine learning to upscale rendered images in real-time. So rather than tasking the GPU with producing a native 4K image, the engine can render the game at a lower resolution and have DLSS make up the difference.
The current model Nintendo Switch
The implications of this technology, especially on computationally limited devices, is immense. For the Switch, which doubles as a battery powered handheld when removed from its dock, the use of DLSS could allow it to produce visuals similar to the far larger and more expensive Xbox and PlayStation systems it’s in competition with. If Nintendo and NVIDIA can prove DLSS to be viable on something as small as the Switch, we’ll likely see the technology come to future smartphones and tablets to make up for their relatively limited GPUs.
But why stop there? If artificial intelligence systems like DLSS can scale up a video game, it stands to reason the same techniques could be applied to other forms of content. Rather than saturating your Internet connection with a 16K video stream, will TVs of the future simply make the best of what they have using a machine learning algorithm trained on popular shows and movies?
Rejoice! Gone are the long chains of if…else statements, because switch statements will soon be here — sort of. What the Python gods are actually giving us are match statements.match statements are awfully similar to switch statements, but have a few really cool and unique features, which I’ll attempt to illustrate below.
Hackaday has always been dark mode. Gray10 is less jarring when you’re burning the midnight oil on a project, so we give you a lot of it. Fifteen years ago, it was called “reverse video” or “trog mode“, and we were the freaks. We were doing it wrong. We had the colors “backwards”. Dark mode used to be edgy, outré, but dare we say it, a bit sexy.
Hackaday … QuickBooks. Just sayin’. They even ripped our highlight yellow!
Flash forward, and everyone has come over to the dark side. Facebook has a dark mode. Google has dark mode. Across the Microsoft empire, from Windows 10 to GitHub, you can live your life in the dark. Heck, even the White House has a dark mode! (They call it high-contrast mode, but they’re not fooling anyone.)
Dark mode here, dark mode there. It’s mainstream. Dark mode has become corporate cool which is nobody’s idea of cool.
We’re not saying that all of the aforementioned institutions are biting the Hackaday style, but, well, they’re all biting our style. Where were they when we were the only website on the whole darn Internet with a sensible background color? Huh? Dark-mode-come-latelys!
But Hackaday doesn’t rest on its laurels. We have our fingers on the pulse on the modern hacker. Where previously you would be up late at night researching Hackaday for juicy nuggets of communal wisdom to help out with your current hack, you’re probably “telecommuting” these days — a euphemism for working on your private projects even while the fiery ball is still in the sky. (Wink, wink, nudge, nudge.) It’s only natural that you’d want a lighter background color to match your new lifestyle. We hear you!
So we present you, Hackaday Light Mode™. Enjoy!
[Editor’s note: For historical accuracy, we had phosphor green headings in the very beginning, in place of the jarring white. If you want to relive those glory days of yore, or just to go back to Hackaday in dark mode, there’s always CSS scripting.]
Car manufacturers will often tout a vehicle’s features to appeal to the market, and this often leads to advertisements featuring a cacophony of acronyms and buzzwords to dazzle and confuse the prospective buyer. This can be particularly obvious when looking at drivelines. The terms four-wheel drive, all-wheel drive, and full-time and part-time are bandied about, but what do they actually mean? Are they all the same, meaning all wheels are driven or is there more to it? Let’s dive into the technology and find out.
Part-Time 4WD
Part-time four-wheel drive is the simplest system, most commonly found on older off-road vehicles like Jeeps, Land Cruisers and Land Rovers up to the early 1990s, as well as pickup trucks and other heavy duty applications. In these vehicles, the engine sends its power to a transfer case, which sends an equal amount of torque to the front and rear differentials, and essentially ties their input shafts together. This is good for slippery off-road situations, as some torque is provided to both axles at all times. However, this system has the drawback that it can’t be driven in four-wheel drive mode at all times. With the front and rear differentials rotating together, any difference in rotational speed between the front and rear wheels — such as from turning a corner or uneven tyre wear — would cause a problem. The drive shaft going to one differential would want to turn further than the other, a problem known as wind-up.
Google giving up on one of their projects and leaving its established userbase twisting in the wind hardly counts as news anymore. In fact, it’s become something of a meme. The search giant is notorious for tossing out ideas just to see what sticks, and while that’s occasionally earned them some huge successes, it’s also lead to plenty of heartache for anyone unlucky enough to still be using one of the stragglers when the axe falls.
So when the search giant acknowledged in early March that they would no longer be selling their Cardboard virtual reality viewer, it wasn’t exactly a shock. The exceptionally low-cost VR googles, literally made from folded cardboard, were a massive hit when they were unveiled back in 2014. But despite Google’s best efforts to introduce premium Cardboard-compatible hardware with their Daydream View headset two years later, it failed to evolve into a profitable business.
Google Cardboard
Of course if you knew where to look, the writing had been on the wall for some time. While the Daydream hardware got a second revision in 2017, and Google even introduced a certification program to ensure phones would work properly with the $100 USD headset, the device was discontinued in 2019. On the software side, Android 7 “Nougat” got baked-in VR support in 2016, but it was quietly removed by the time Android 11 was released in the fall of 2020.
With Cardboard no longer available for purchase, Google has simply made official what was already abundantly clear: they are no longer interested in phone-based virtual reality. Under normal circumstances, anyone still using the service would be forced to give it up. Just ask those who were still active on Google+ or Allo before the plug was pulled.
But this time, things are a little different. Between Google’s decision to spin it off into an open source project and the legions of third party viewers on the market, Cardboard isn’t going down without a fight. The path ahead might be different from what Google originally envisioned, but the story certainly isn’t over.
Pens! They just might be the cheapest, most important piece of technology ever overlooked by a large group of people on a daily basis. Pens are everywhere from your desk to your car to your junk drawer, though they tend to blink out of existence when you need one. Where would we be without them? Probably still drawing on cave walls with dandelions and beets.
Why do I think pens are so great? Well, they’re a relatively cheap tool depending on the pen you get, but whatever you spend, you’re getting a lot for your money. Pens are possibility, pure and simple, and they’re even conveniently packaged in a portable device.
Aesthetically speaking, I like pens because of how different they can be both inside and out. Some of them make thick lines, some make thin lines, and in the case of flexible nibs, some alternate between thick and thin lines depending on pressure. I use pens for a number of reasons, most notably for writing. Everything you read here that bears my name began life as pen marks on paper.
Pens are revolutionary because they can be used to make ideas permanent and/or illustrate any concept. It’s up to you to use the pen wisely. You can use other, better tools later, but pens are always a great first tool. If you’re not encumbered by an uncomfortable grip, ink that skips, or a scratchy, draggy contact point, your ideas will flow more freely. When you find the right pen for you, you aren’t hindered by your tool — you’re elevated by it. Continue reading “A Few Of My Favorite Things: Pens”→
